Yeah I would stay away from those TSUDO headers on ebay too. You do have to be careful, that's for sure. I can't really say I've been scammed though, I'm pretty scrupilous before buying. I try to buy things that I can physcially go and pick up, if they are cool with that, then it's usually pretty legit. Kamikaze aint all that bad, Import Tuner did a piece on them and it happens to be one of the most sought after inexpensive headers for supercharged cars. Kamikaze is one of the few co. that make a header w/2.5 piping.
